I stumbled across this line of food tonight. It is called Great Life "Rubicon" dog food, which is grain-free & potato-free. Anyone ever heard of it? This company makes some interesting statements about the use of potato in dog foods.

Acrylamide
This is a carcinogenic compound formed at cooking temperatures of about 250°F in foods containing certain sugars and the amino acid asparagine (found in large amounts in potatoes and cereal grains). It is formed in a chemical process called the Maillard reaction.4, 5 Most dry pet foods contain cereal grains or potatoes, and they are processed at high temperatures (200–300°F at high pressure during extrusion; baked foods are cooked at well over 500°F); these are perfect conditions for the Maillard reaction. In fact, the Maillard reaction is considered desirable in the production of pet food because it imparts a palatable taste, even though it reduces the bioavailability of some amino acids, including taurine and lysine.6 The content and potential effects of acrylamide formation in pet foods are unknown.

However, studies in human populations have failed to produce consistent results, and it remains unclear whether this is due to a reduced risk in a natural setting or the methodological difficulties inherent in such studies. For example, it might be difficult to isolate the effects of acrylamide because it is so ubiquitous in Western diets.
